Title: Push button switch
Inventor: TAKANO TSUNESUKE
IPC: H01H13/12
Filed: 1991-09-11
Abstract: A push button switch comprises a pair of fixed contacts (3, 4) disposed partially opposite to each other on opposed inner walls of an insulating cylinder (1). A push button (8) is fitted with a generally U-shaped movable contact (5) which can make sliding contact with each of the fixed contacts (3, 4), and is assembled into the cylinder (1) against a spring (6) between the push button (8) and a spring support (1d) of the cylinder (1). Resilient locking parts on the push button (8) are engageable with locking tabs on the cylinder (1) to define the outer position of the push button (8), the resiliency of the locking parts permitting assembly of the push button into the cylinder. Both ends (5b) beyond contact portions (5a) of the movable contact (5) engage inner edges of holes (8b) in the push button (8), when the movable contact (5) is fitted onto a center boss (8a) of the push button (8) so as to prevent the movable contact (5) from coming off the push button (8) thereby facilitating assembly. <IMAGE>

Title: Electron gun sealing apparatus
Inventor: CHOI DAE-OK
IPC: C03B23/217
Filed: 1991-11-01
Abstract: For the manufacture of a cathode ray tube, an electron gun sealing apparatus comprises a bulb supporting means 20 for supporting a bulb 100, a first up/down means 30 for raising and lowering an electron gun. which is vertically positioned below the bulb 100, a heating means 40 arranged around the neck 101 of the bulb to heat the neck 101 and the stem of the electron gun, a second up/down means 50 for raising and lowering the heating means 40 to a certain height in relation to the neck 101, and a revolving means 60 for rotating the heating means with respect to the electron gun supporter. The various different moving mechanisms and locating arrangements of the apparatus are disclosed in detail in Figs. 3-11 (not shown). Since the sealing by the sealing apparatus is performed by rotating the heating means 40, which is formed by a plurality of burners, Fig. 7 (not shown), the bulb 100 is free from centrifugal force, thus preventing displaced sealing of the neck. Also, thinning and cracking at the seal is prevented by an accurate position control and a sealing flame adjustment. Further, this automatically performed sealing operation simplifies the sealing, reduces labour, and improves productivity. <IMAGE>

Title: Method for positioning of sheet metal workpiece in bending press
Inventor: SARTORIO FRANCO
IPC: B21D43/00
Filed: 1991-11-21
Abstract: The method comprises the calculation of the spacing of the actual plate position when held adjacent the machine by a manipulator and a desired position, and the movement of the plate to the desired position by repeating the action of moving the plate which shortens the spacing in a specified ratio. Two spaced backgauges 17 aligned parallel to the bending axis detect when the plate W is approaching the desired position and if the plate is tilted from the ideal axis for bending purposes. The angle ratio, of the tilting, and the distance during the approach are the factors having the decreasing ratio step movements applied to them. <IMAGE>

Title: Method of and equipment for setting the torque of an internal combustion engine
Inventor: HESS WERNER
IPC: F02P5/145
Filed: 1993-09-29
Abstract: A method of setting the torque of an internal combustion engine makes use of induction air mass flow and ignition angle. The actual torque is normalised for a target ignition angle (ZW_SOLL), whereby the ignition-angle-dependent component in the actual torque is not taken into consideration in the torque thus ascertained. The normalised torque value (@_ZWORM) is compared with a target torque value (M_SOLL) in order to obtain a torque deviation ( DELTA M), from which an integration value (M_INT) is formed and employed to modify the target torque (M_SOLL) to obtain an effective torque value (M_EFF), which in turn influences the determination of a control angle ( alpha ) for the engine throttle flap. The torque deviation ( DELTA M) is also used to modify an ignition angle deviation ( DELTA ZW), which in turn modifies a target ignition angle (ZW_SOLL) to provide an actual ignition angle (ZW_AKT). <IMAGE>

Filed: 1994-09-19
Abstract: An audio reproducing apparatus includes an audio reproducing unit fitted into a listener's ears to reproduce the digital audio signals supplied thereto from a signal source 1 or 2 by an electro-acoustic transducer. An address signal generating unit generates an address signal the listener's head motion relative to a standard direction.
